Unfortunately, the only way to get fairly nice looking fonts on Linux is to use a 4k display :-( Even with font hinting, the quality you are used to from OS X or even Windows isn't there, and most people that develop Linux don't seem to have developed sensitivity for font quality, so you should not expect any improvements. Any time I look at my Debian server, I have that strange unpleasant feeling of fonts being somehow off. Ubuntu/Mint are better, yet still nowhere near the clarity of OS X.
